Today one of my chickens (don’t know which one though) pooped something that looked like a tapeworm, but not sure if it is. One of my chicken has been having this problem of laying shell less eggs and ive given her caltrate and things but still no improvement. If it was a worm I would guess it is her. I have dewormed them many times. Here is the picture of what seems to be a worm. Could you give some ideas if it’s a worm and what I should do?
